First of all: try to figure out which command line arguments you can pass to the export command. Then select the ones you're going to need.
Have a go at the command line with some of those command line arguments (PARFILE is a nice one)

If you succeed in running exp with command line arguments without exp asking you for more, then you just have to put the command line with its arguments in a shell script.

All this and much more you'll find in the manuals Wink

And how do you know it's not working?
Do you get an error? If so: what error would that be?

And what does command not found tells you ?

I guess you're running Unix (or any flavour of Unix).

Scripts started from within CRONTAB behaves a bit different than the ones you start at the command line.

Some start-up stuff that's executed when you log in at the system, isn't executed when a crontab-job is started.
When you log in the ORACLE_HOME is set, as long with the PATH evironment variable.
And that's what missing in your script so it can be run succesfully via crontab.

Ask your unix-administrator to help you out on this.

Adding to Marc's answer, crontab runs with NO environment. You have to set all variables including your PATH.
Try just creating a dummy script to select sysdate from dual, set it to run 1 minute from now, and then see the output and fix accordingly.
